0x800a138a-JavaScript运行时错误:AJAX调用中需要函数
请参阅下面的代码:0x800a138a-JavaScript运行时错误:AJAX调用中需要函数,javascript,jquery,asp.net,ajax,vb.net,Javascript,Jquery,Asp.net,Ajax,Vb.net,请参阅下面的代码: <script type="text/javascript" src="Javascript/json2.js"></script> <script type="text/javascript" src="Javascript/jquery-1.11.1.min.js"></script> <script type = "text/javascript"> function GroupUSNChange(

函数GroupUSNChange(){
警惕(“到达这里”);
var frm=document.forms[0];
var usn=document.getElementById(“ctl00\u ContentPlaceHolder1\u hfUSN”);
对于(i=0;i
以及背后的代码:
<System.Web.Services.WebMethod()> _
Public Shared Function ChangeGroupOfUSNs(ByVal strNewUSN As String, ByVal strURNs As String, ByVal strDatasetName As String) As String
Dim intUSN As Integer = CInt(strNewUSN)
Return "done"
End Function
_
公共共享函数ChangeGroupOfUSNs(ByVal strNewUSN作为字符串,ByVal strURNs作为字符串,ByVal strDatasetName作为字符串)作为字符串
作为整数的Dim intUSN=CInt(strNewUSN)
返回“完成”
端函数
错误出现在起始行:$.ajax({
id和USN包含正确的值。为什么会出现此错误?您正在调用成功处理程序:
success: OnSuccess(response),
^^^^^^^^^^
当它应该更像:
success: function(data) { OnSuccess(data); }
您正在呼叫您的成功处理程序:
success: OnSuccess(response),
^^^^^^^^^^
当它应该更像:
success: function(data) { OnSuccess(data); }
